disable week selection button in calendar

Hello,

I have a calendar that have some days disabled (i.e. past dates)

Is there a way to also disable the week selection button in a similar way?

Sub Day_Render(ByVal sender As Object, ByVal e As DayRenderEventArgs) Handles clDate.DayRender

If _disablePastDates Then

If e.Day.Date < Today.AddDays(1) Then
